Papers—( 1) “On the Pycnogonide, with descriptions ot two 
species,’ by Geo. M. Thomson, F.L.S. The author points out 
that only five species of this remarkable family have, yet been 
found in New Zealand, Of these, two species of Nymphen and one 
of Oorhynchus were found in our seas (at very considerable depths) 
during the voyage of |the “Challenger,” and are described at p. 
170 of this journal. A species of Ammothea was ‘recorded by the 
author at p. 28 of this journal, but as the description there given 
(translated from Quatrefages) is most imperfect and cannot be 
with certainty applied to any known species, a new and full de- 
scription of our species is given under the provisional name of 
Ammothea (Achelia) dohrni. The second species described is a new 
Pallene (P. nove-zealandie), of which one specimen was obtained by 
the dredge in Otago Harbour.

Numerous specimens ot this species (including one male) were ob- 
tained last year by Mr C. Chilton, in ponds near Eyreton, Canter- 
bury, and were sent to the author. The animals when alive were 
ot a brick-red colour. They closely resemble the common 
European J. pulex, and may possibly be only a variety of that 
species. The chief difference lies in the very acute rostrum of the 
female, and in the anterior antenne being represented by a very 
minute tubercle, which is quite destitute of setee. In the male the 
beak is blunt, while in both sexes the carapace is posteriorly 
produced into a stout spine. The species is named D. similis. 
Several specimens illustrative of both papers were exhibited 
under microscopes. 
Mr. R. Gillies took occasion to welcome Mr. Thomson back to 
the Institute meetings, and to express the sympathy of the mem- 
bers with him in consequence of his long illness. 
Prof. Parker remarkedion the fact that the Crustacea of New Zea- 
land were now becoming pretty well known, owing to the researches 
of Mr. Thomson and others, and expressed a hope that workers 
might be got to take up the study of the numerous other inverte- 
brate groups, about which at present very little was known, 
(3.) “On a Torpedo recently caught near Dunedin,” by Prof. 
T. J. Parker. The specimen described was caught at Purakanui 
towards the end of last year. In most respects it agrees with
